git_stash_pop · PSKit MCP: Risk & Policy

WHAT IT DOES

What git_stash_pop does on PSKit

AI agents use git_stash_pop to create or update resources in PSKit — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PSKit environment.

WHY IT NEEDS A POLICY

Why git_stash_pop needs a policy

git stash pop applies previously stashed changes back to the working directory, modifying files. This is a reversible write operation (changes can be re-stashed or reverted), but misuse could overwrite working directory changes or cause merge conflicts. It does not execute arbitrary code or permanently delete data.

git_stash_pop Rate-limited

git_stash_pop stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
